1 1 2 FIGS.A,B, and 100 110 120 130 140 150 160 Referring to, the display apparatusaccording to one embodiment of the present specification includes a front member, an adhesive layer, a polarizing plate, a display panel, a second plate, and a first plate.

140 140 The display panelmay be a panel on which an image is displayed. For example, the display panelincludes a display device for displaying the image and a circuit, a wiring, and components for driving the display device.

1 1 FIGS.A andB 140 Referring to, the display panelincludes a display area AA, a non-display area NA, and a camera area CA.

100 100 The display area AA is the area in which a plurality of sub-pixels SP are disposed to display the image. Each of the plurality of sub-pixels SP is an individual unit for emitting light. The light emitting device and the driving circuit are formed in each of the plurality of sub-pixels SP. For example, the display device for displaying the image and the circuit unit for driving the display device may be disposed in each of the plurality of sub-pixels SP. For example, when the display apparatusis the organic light emitting display apparatus, the display device may include an organic light emitting device. When the display apparatusis a liquid crystal display apparatus, the display device may include a liquid crystal display device. The plurality of sub-pixels SP may include a red sub-pixel SP, a green sub-pixel SP, a blue sub-pixel SP, and/or a white sub-pixel SP, but is not limited thereto.

The non-display area NA is the area in which the image is not displayed. The non-display area NA is the area in which various wirings, driving ICs, and the like for driving the plurality of sub-pixels SP disposed in the display area AA are disposed. For example, the various ICs such as a gate driver IC and a data driver IC and the driving circuits may be disposed in the non-display area NA. For example, the non-display area NA may be a bezel area, and it is not limited to terminology.

1 FIG.A The non-display area NA may be the area surrounding the display area AA as shown in. The non-display area NA may be the area extending from the display area AA. Further, the non-display area NA may be the area in which the plurality of sub-pixels SP are not disposed. However, the non-display area NA is not limited thereto.

100 140 A camera area CA is disposed inside the display area AA. The camera area CA is disposed between the plurality of sub-pixels SP in the display area AA. In the camera area CA, optical components such as a camera and an optical sensor are disposed. The optical sensor may include a proximity sensor, an infrared sensor, an ultraviolet sensor, and the like. A hole H penetrating a part of the display apparatusis formed in the camera area CA to arrange the optical component. By forming the hole H penetrating the display panel, a space in which the optical component is disposed may be formed.

170 Some of the light emitted from the plurality of sub-pixels SP may propagate toward the camera area CA disposed between the plurality of sub-pixels SP, for example, the hole H. When light propagating from the plurality of sub-pixels SP to the hole H is reached to the optical component such as the camera, noise may be generated and thus reliability of the optical component may be deteriorated. Accordingly, the light blocking membermay be disposed in the hole H so that light is not reached to the hole H.

110 140 110 130 140 110 110 110 110 The front memberis disposed over an upper surface or at a front of the display panel. The front membermay protect the polarizing plateand the display panellocated under the front memberfrom external impact, moisture, heat, and the like. The front membermay be made of the material having impact resistance and light transmittance. For example, the front membermay be a substrate made of glass or a thin film made of a plastic material such as polymethylmethacrylate (PMMA), polyimide (PI), or polyethylene terephthalate (PET), but is not limited thereto. Further, the front memberis an exemplary name, and may be expressed by various names such as a cover window and a cover glass, but is not limited thereto.

130 110 140 130 140 140 140 100 130 140 100 130 130 100 2 FIG. The polarizing plateis disposed between the front memberand the display panel. The polarizing plateselectively transmits light to reduce the reflection of external light incident to the display panel. That is, various metal materials applied to the thin film transistors, the wirings, the light emitting device, and the like are disposed in the display panel. External light incident to the display panelmay be reflected by the metal material, and thus the visibility of the display apparatusmay be reduced due to the reflected external light. Since the polarizing plateis disposed on one side of the display panelto prevent reflection of external light, the outdoor visibility of the display apparatusmay be improved. However, the position of the polarizing plateillustrated inis exemplary, and the polarizing platemay be omitted depending on the structure of the display apparatus.

120 130 110 120 110 130 120 120 The adhesive layermay be disposed between the polarizing plateand the front member. For example, the adhesive layermay adhere the front memberon the polarizing plate. The adhesive layermay be made of the material having adhesive properties. For example, the adhesive layermay be formed of an optical clear adhesive (OCA), a pressure sensitive adhesive (PSA), or the like, but is not limited thereto.

150 140 140 100 140 140 150 140 150 140 140 150 150 The second plateis disposed under the display panel. When the substrate of the display panelis made of the plastic material such as a polyimide, the manufacturing process of the display apparatusis performed while a support substrate made of glass is disposed under the substrate, and the supporting substrate may be separated from the display panelafter forming the components such as the polarizing plate on the display panel. For example, since the components for supporting the substrate are required even after separation of the supporting substrate, the second platefor supporting the substrate may be disposed under the substrate of the display panel. The second platemay support the display paneland protect the display panelfrom external moisture, heat, impact, and the like. The second platemay be, for example, the thin film made of polyimide (PI), polyethylene terephthalate (PET), polyethylene naphthalate (PEN), or the like. The second platemay be expressed in various terms such as a back plate or an auxiliary plate, but is not limited thereto.

160 150 160 160 160 160 100 160 110 170 160 160 160 The first plateis disposed under the second plate. The first platemay protect and support the components disposed on the first plate. Since the first plateis made of a rigid material, it is possible to minimize the occurrence of dent marks and the like due to the external impact. The first platemay be a heat sink member that radiates heat generated when the display apparatusis driven. Further, the first platemay be made of the excellent electrical conductive material, and thus may discharge static electricity generated in the front membertogether with the light blocking memberto the outside. The first platemay be made of the material having excellent thermal and electrical conductivity. For example, the first plateis made of at least one of a copper (Cu), a copper foam (Cu foam), a stainless steel, a graphite, the polyethylene terephthalate (PET), these of an alloy material, and a bonding structure thereof. For example, the first platemay be made of the alloy material of stainless steel and copper, and the like, but is not limited thereto.

160 Further, the first platemay be expressed in various terms such as a metal plate, but is not limited thereto.

160 A step is formed at an edge of the first plate.

160 110 130 150 160 140 160 140 160 160 140 200 160 140 160 160 140 160 140 140 3 FIG. Conventionally, the first plateis made of the rigid material to protect and support the components disposed thereon, such as the front member, the display panel, and the second plate, from external impact. For example, the first platemay be made of metal. But, in this case, the display paneland the first platecannot be simultaneously cut. When the display paneland the first plateare cut using a laser at the same time, the processing time is prolonged due to the material and thickness of the rigid first plateand the display panelmay be damaged due to the strong energy of the laser(see). Accordingly, when the first plateis made of metal, there is the problem in that the display paneland the first platecannot be cut at the same time. Conventionally, due to this problem, the first plateis attached after cutting the display panel. However, when the first plateis attached after cutting the display panel, there is the problem in that the edge of the display panelcannot be supported due to a process margin. In order to solve this problem, the inventors of the present specification have studied various methods for simultaneously cutting the display panel and the first plate and reducing damage to the display panel. Through these studies, the display apparatus capable of minimizing damage to the display apparatus from the external impact applied to the side surface of the display apparatus was invented.

3 FIG. is the view illustrating the process of cutting the display panel and the first plate by the laser.

2 3 FIGS.and 100 130 140 150 140 160 150 200 160 160 150 140 130 160 150 140 130 140 160 140 160 110 130 120 140 160 140 160 Referring to, when the display apparatusis fabricated, the polarizing plateis disposed above the display paneland the second plateis disposed under the display panel. Thereafter, the first platehaving the step at the edge thereof is disposed at the lower side of the second plate. Subsequently, the laser beam from the laseris irradiated to the upper surface of the first plateto cut the first plate, the second plate, the display panel, and the polarizing plate. Therefore, the cutting faces or side faces of the first plate, the second plate, the display panel, and the polarizing plateare formed in a straight line without the step, a slope, and a curvature. For example, the display paneland the first platemay have a same plane in a vertical direction, meaning that outer peripheral edges or outer surfaces of the display paneland the first plateare aligned along a vertical plane positioned at the outer peripheral edges or outer surfaces. After the cutting process by the laser is terminated, the front memberis attached on the polarizing plateby the adhesive layer. The display paneland the first platemay be cut in the same process. The display paneland the first platemay include the same plane by the same process.

160 140 160 In accordance with the embodiment of the present specification, since the thickness at the edge of the first plateis small by the step, the display paneland the first platemay be simultaneously cut.

160 160 160 The step of the first platemay be formed by the chemical etching process. For example, a photo-resist pattern is formed on the first plateexcept the edge and then the edge of the first plate is etched using the photo-resist as an etching mask to partially remove the first plate.

160 1 2 160 1 160 2 160 2 160 1 160 5 FIG. Due to the step at the edge, the first platemay have at least two thicknesses. The thickness Tof the edge may be smaller than the thickness Tof other area of the first plateby the step (see). The thickness Tof the edge of the first plateis ½ to ⅓ of the thickness Tof the first plate. For example, when the thickness Tof the first plateis 90 μm, the thickness Tof the edge of the first platemay be 30 μm to 45 μm.

1 160 140 2 160 140 The area of the first thickness Tof the first platemay be overlapped with the non-display area NA of the display panel. The area of the second thickness Tof the first platemay be overlapped with the display area AA and a part of the non-display area NA of the display panel.

160 According to the embodiment of the present specification, the step of the first platemay have a right angle shape.

4 4 FIGS.A andB 2 FIG. are other cross-sectional views of.

4 FIG.A 4 FIG.B 160 160 Referring to, which is other example of the present specification, the step of the first platemay have a curved shape such as a round shape. Referring to, which is another example of the present specification, the step of the first platemay have a stair shape at a right angle, meaning a step-down or step-up shape with right angles between the steps. For example, the shape of the step may be formed in various shapes such as the right angle, the round shape, and the stair shape by controlling an etching rate.

160 160 For example, if the first plateis etched at a high speed, the step is formed in the right-angled shape. If the first plateis etched at a slow speed, the step is formed in the round shape. Further, if additional photoresist patterning process is added, the step may be formed in the stair shape.

160 140 140 160 140 140 Since the first platesupports the lower surface of the display panel, the strength of the display paneland the display apparatus can be reinforced. Further, since the edge of the first plateoverlaps with the edge of the display panel, the strength of the side surface of the display apparatus can be reinforced, and thus the damage to the display paneland the display apparatus caused by the external impact may be minimized.

1 5 FIGS.B and Hereinafter, another embodiment of the present specification will be described with reference to.

1 FIG.B is an enlarged plan view of the camera area within the display area.

5 FIG. 2 FIG. 5 FIG. 2 FIG. 170 Comparing the display apparatus ofwith the display apparatus of, the structure of the display apparatus ofis substantially same as the structure of the display apparatus ofexcept the light shielding memberdisposed in the camera area CA. Thus, duplicated description will be omitted.

130 140 150 160 110 A part of the polarizing plate, the display panel, the second plate, and the first plateunder the front membermay be cut to form the hole H in which the camera and the optical components are disposed. Further, a portion of the display apparatus may be cut in the form of a notch, and various types of regions in which the optical components may be disposed may be formed in the display apparatus.

100 110 120 130 140 150 160 110 110 The hole H is formed in the components of the display apparatusexcept for the front member. The hole H penetrates the adhesive layer, the polarizing plate, the display panel, the second plate, and the first plate. The hole His an empty space for arranging the optical component such as the camera in the display area AA. The optical component may be disposed in the hole H to recognize the external environment outside the front member. Since the hole H is not formed in the front member, it is possible to prevent impurities from penetrating into the hole H.

160 160 120 130 140 150 1 160 2 The size of the hole H of the first platemay be determined according to the step structure of the first plate. The hole H continuously formed in the adhesive layer, the polarizing plate, the display panel, and the second platemay be a first hole H. The hole formed in the first platemay be a second hole H.

5 FIG. 1 1 120 130 140 150 160 2 160 160 For example, referring to, the first hole Hhaving a first diameter Dis formed in the adhesive layer, the polarizing plate, the display panel, and the second plate. The step is formed by etching the edge of the first platewithin the second hole H. The portion in which the first plateis not etched may be a first portion. The portion etched by the etching process in the edge of the first platemay be a second portion.

2 160 1 120 130 140 15 2 160 1 120 130 140 150 The second hole Hof the first platemay overlapped with the first hole Hformed in the adhesive layer, the polarizing plate, the display panel, and the second plate. The first portion of the second hole Hof the first platemay be overlapped with the first hole Hformed in the adhesive layer, the polarizing plate, the display panel, and the second plate.

160 150 140 130 140 160 140 The cut face of the first plate, the second plate, the display panel, and the polarizing platedisposed in the camera area CA of the display area AA is formed in the straight line without the step, the slope, or a curvature. For example, the display paneland the first platemay have the same face in the vertical direction of the display panel.

160 160 160 1 160 2 160 1 160 2 160 2 160 1 160 Due to the step at the edge, the first plateof the camera area CA may have at least two thicknesses. Since the step is formed at the edge of the first plateby etching the edge of the first plate, the thickness Tof the edge of the first plateis smaller the thickness Tof the first plate. The thickness Tof the edge of the first plateis ½ to ⅓ of the thickness Tof the first plate. For example, when the thickness Tof the first plateis 90 μm, the thickness Tof the edge of the first platemay be 30 μm to 45 μm.

1 2 160 1 160 2 1 160 The diameter Dof the first portion of the second hole Hof the first platemay have the same diameter as the first hole Hof the first plate. The diameter Dof the second portion may be larger than the diameter Dof the first portion of the first plate.

1 160 140 1 160 140 2 160 140 The area of the first thickness Tof the first plate, which is disposed in the cameral area CA, may be overlapped with the non-display area NA of the display panel. The area of the first thickness Tof the first platemay be overlapped with the non-display area NA of the display panel. The area of the second thickness Tof the first platemay be overlapped with the display area AA and a part of the non-display area NA of the display panel.

160 The step of the first plateformed in the camera area CA has the right-angled shape.

6 6 FIGS.A andB 1 FIG.B are views according to another embodiment of the present specification, and are cross-sectional views taken along line II-II′ of.

6 FIG.A 6 FIG.B 160 160 Referring to, the step of the first platemay be formed in the round shape. Referring to, the step of the first platemay be formed in the stair shape of the right angle. For example, the shape of the step may be formed in at least one of the right angle, the round shape, and the stair shape by controlling an etching rate.

160 160 For example, if the first plateis etched at a high speed, the step is formed in the right-angled shape. If the first plateis etched at a slow speed, the step is formed in the round shape. Further, if additional photoresist patterning process is added, the step may be formed in the stair shape.

160 140 140 160 140 100 140 100 100 Therefore, since the first platecan support the display panelwithin the camera area CA, the strength of the display paneland the display apparatus is reinforced. Further, since the edge of the first plateis overlapped with the edge of the display panel, the strength of the side of the display apparatusis reinforced, it is possible to minimize damage to the display paneland the display apparatusfrom the impact generated during the subsequent process of mounting the camera inside the hole H or the external impact applied to the display apparatus.

The light blocking membermay cover inner side surfaces of the first hole Hand the second hole H. For example, the light blocking membermay be disposed to cover a portion of the rear surface of the front memberin the hole H. For example, one end (or a portion) of the light blocking membermay be disposed on the rear surface of the front memberand the other end (or other portion) may be overlapped with a portion of the first plate.

170 160 160 As another example of the present specification, the light blocking membermay cover only the side surface of the first plateand may not cover the rear surface of the first plate.

170 170 170 The light blocking membermay be made of conductive ink or conductive paste. For example, the conductive paste may include conductive particles such as carbon black, conductive ink mixed with conductive polymers such as PEDOT:PSS (poly(3,4-ethylenedioxythiophene)), or a material such as silver (Ag). For example, the light blocking membermay have a resistance of 0 to 106Ω to discharge static electricity. The light blocking membermay be formed of various materials other than the above-described materials, but is not limited thereto.
